Abstract

Part of the outer wall of the waste bin (10) is formed by the external side of the inserted container (11). The container (11) is made of dimensionally-stable material and is partially transparent.

Description

The present invention relates to a refuse container according to the preamble of claim 1 protection.

On waste containers, especially on waste containers that are placed in public places, such as public parks, stops of public transport, pedestrian areas, parking lots, motorway service areas or the like, special requirements. On the one hand, the refuse containers must be able to be fixed in order to prevent them from stealing or knocking over. Nevertheless, the waste containers must be easy to empty and should have a long life in order to minimize costs.

EP 0 150 093 A2 describes such a refuse receptacle, which has a housing which can be connected to a base, and in which housing a container is accommodated, which can be removed from the base after removal of the housing for emptying , In this case, the housing completely surrounds the container and has an opening in the upper area, through which waste can be brought into the container.

The disadvantage of such known waste containers is that an insight on the contents of the container only from above is possible and only if the housing has been removed, is possible without hindrance. Although this lack of visibility of the contents of the container may be desirable for aesthetic reasons. For reasons of practicability and in particular safety, it is necessary at any time to allow insight into all items in the container. So can be easily recognized only in this way, the degree of filling of the container and possibly deposited in the waste container hazardous substances, such as explosives, are detected.

Object of the present invention is thus to provide a waste container, which meets the requirements for waste containers and beyond the view into the interior of the refuse collection container, in particular easy on the content and in which the visibility of the interior of the refuse collection container are maintained over a long time can. In addition, the waste container should be inexpensive to produce and the maintenance costs should be low.

The invention is based on the finding that this object can be achieved by a waste container comprising two parts, wherein a part is interchangeable and the visibility of the interior of the refuse collection container is given by this replaceable part.

The object is achieved by a waste container with the features according to the protection claim 1. Further advantages, features, details, aspects and effects of the invention will become apparent from the dependent claims, the description and the drawings.

The waste container according to the invention comprises an insert container and a holding device for the insert container, wherein the insert container is detachably connected to the holding device. The waste container is characterized in that a part of the outer wall of the waste collection container is formed by a part of the outside of the insert container, wherein the insert container consists of dimensionally stable material and is at least partially transparent.

By dividing the waste collection container into a holding device and an insert container, the materials of the individual components can be selected that they can take sufficient account of the relevant requirements. Thus, a material can be selected for the insert container, which can provide in particular the required stability. Damage to the container, which would result in a hole that could drop through the waste from the insert container, can thus be reliably avoided.

Moreover, according to the invention, since a part of the outer side of the insert container forms part of the outer wall of the refuse container, the choice of a transparent material for at least this area can ensure the insight into the interior of the insert container, in particular the lateral view of its contents. The viewer can look at the interior of the insert container from the side and thus can also see objects that lie under other objects and are thus covered from above. This viewing direction is particularly advantageous for the discovery of explosives and the like, since they are usually covered and therefore can not be detected in conventional waste containers.

The use of an at least partially transparent use container also has the advantage that people are deterred from dumping hazardous substances in the waste container due to "social control".

Although it is possible to manufacture only the part of the feed container which forms part of the outer wall in the refuse container from transparent material, preferably the entire feed container is made of transparent material. As a result, the production of the insert container can be simplified and the production costs can be reduced. The transparent material may also include a dye to enhance the appearance of the waste collection bin through a colored yet transparent use bin.

Since the insert container is detachably connected to the holding device, the insert container can be removed and replaced if necessary. hereby It is possible to ensure the visibility of the contents of the insert container over a longer period of time. If an insert container has become a victim of vandalism, for example, smeared with graffiti or so damaged, for example, scratched that the transparency is no longer given, the insert container can be replaced. However, if the insert container is only dirty due to prolonged use, for example, it can be removed from the holding device and cleaned on site or in a central cleaning station. In this way, the life of the refuse collection container, which should be five to ten years, determined only by the life of the holding device. However, in the construction according to the invention, the holding device only has to fulfill the requirement of sufficient stability and can thus be produced from a wear-resistant material, for example metal or plastic, and in a robust construction, in particular with greater wall thickness. With this construction and this material can thus be achieved a long life of the holding device and thereby also the refuse collection container according to the invention, at the same time the visibility of the interior of the insert container can be ensured even after a long time. Since, in order to maintain visibility from the side, only the use container needs to be replaced or only cleaned, which can be manufactured inexpensively, the costs for the waste collection container can be kept to a minimum.

The insert container according to the invention preferably made of plastic, in particular a thermoplastic material. The feed container is preferably made by a stretch blow molding method, an injection molding method, or a combination of these methods.

Particularly preferably, the insert container is made of polyethylene terephthalate (PET). This material has the properties desired according to the invention. Since PET is a thermoplastic, it can be molded under heat and made into almost any shape. It can thus be made with a desired wall thickness, an insert container, the having required dimensional stability. In addition, PET has a high chemical resistance, so cleaning agents, especially chemical cleaning agents that may be necessary to remove contaminants, can be used without damaging the insert container. Furthermore, PET can be used several times, that is, subjected to recycling.

In addition, since the material and the processing of PET are inexpensive, a large number of feed containers can be produced for a waste container without increasing the cost of the waste container beyond measure.

In order to facilitate the emptying and cleaning of the insert container, the insert container preferably has a smooth surface on the inside. In this way, a settling of waste residues on the inside can be largely avoided and a cleaning and complete emptying can be carried out reliably.

In addition or as an alternative to the smooth design of the inside of the insert container, the latter may have on its inside and / or outside a coating, in particular a water-repellent coating. For example, a material can be used for the coating, which causes the so-called lotus effect to occur. Such coatings have a highly hydrophobic surface with a special microstructure, which greatly reduces the contact area for water and dirt. Dirt particles can therefore not adhere and are entrained by a bead-off liquid. By such a coating, the need for cleaning the insert container, in particular on a cleaning of the outside, can be reduced if the waste container is set up, for example, outdoors.

On the outside, in one embodiment, the insert container can have unevenness, at least in the region which forms part of the outer wall of the refuse collection container. These bumps can be, for example, grooves or Be surveys. Due to these unevenness on the outside, this no longer forms a suitable surface for attaching posters. As a result, the viewing area over which the contents of the insert container can be seen, no longer be blocked. The unevenness can also be provided on the holding device.

The insert container has a filling / emptying opening in the upper region, via which waste can be introduced into the insert container and over which it can be emptied. Preferably, the opening for filling and emptying is provided on the upper side of the feed container, and the cross section of the feed container is constant or decreases from this opening to the lower side, that is to the bottom of the feed container. This shape of the insert container allows the insert containers stacked inside each other. As a result, the service of emptying, cleaning or disposal of use containers is simplified and it can be saved storage space.

The holding device preferably represents a clamping device, in which the insert container is held by clamping force between at least two elements of the holding device. It is within the scope of the invention but also possible to use other types of connection between the holding device and the insert container. Thus, the connection between the holding device and the insert container can be provided by the provision of grooves on the holding device, in which the insert container is inserted, or it can be produced a screw connection between the holding device and the insert container. However, a clamping connection between the holding device and the insert container has the advantage that on the insert container no, especially designed for the connection with the holding device, connecting elements, such as webs to insert or screw holes, must be provided. Thus, the structure of the insert container can be kept simple, whereby it can be produced more cheaply. The clamping device preferably acts only in the edge region of the insert container, in particular on two sides and if necessary in the area of the soil. As a result, the holding device must come into contact with the insert container only in this area, as a result of which the lateral inspection of the contents of the insert container can be ensured over the remainder of the insert container.

The holding device may according to one embodiment comprise a frame, which is connected via a hinge or hinge with a further part of the holding device. The further part of the holding device may for example be another frame or a back part, for example in the form of a plate or a stand. About the joint of the frame can be pivoted relative to the other part of the holding device. By pivoting the holding device can be opened and access to the insert container is made possible.

However, the holding device can also be formed by an outer container, which essentially has the shape of the insert container and receives it in itself. The outer container has in this embodiment over a portion of its circumference a recess. In this area, the outer wall of the waste collection container is thus formed by the outside of the insert container and allows the insight into the insert container.

The holding device is preferably always designed so that it allows the lateral view of the contents of the insert container over as large a part of the height of the insert container and the largest possible part of the width of the insert container.

The holding device may preferably comprise a fixing element. This can be provided for example on the lower side of the holding device or on the rear side of the holding device. By means of this fixing element, the holding device can be fastened, for example, to the ground, to a wall or a frame, and a removal of the waste collection container from its position be prevented. The fixing element may be a screw hole, a latching device or the like.

The shape of the refuse collection container and in particular the use container is not limited to a specific form. The insert container may for example be cylindrical or conical and, for example, have a round, oval or rectangular cross-section.

FIG. 1 shows a waste container 10 according to a first embodiment of the invention. This waste container 10 comprises a feed container 11 and a holding device 12. The holding device 12 is formed in the illustrated embodiment on the front by a frame 13 having an opening 14. As can be seen in FIG. 2, the holding device 12 comprises on the rear side a rear part 15, which in the closed state is separated from the frame 13 is covered. The rear part 15 may for example be a plate, have a frame shape or consist of two rails that can be brought to me the two lateral ends of the frame 13 into engagement. The connection between the frame 13 and the rear part 15 is formed in the illustrated embodiment via a hinge 16 in the lower region of the frame 13 and the rear part 15 and a latching or closing device 17 in the upper region of the frame 13 and the rear part 15.

In the holding device 12, an insert container 11 is received. On the other hand, the height of the opening 14 of the frame 13 is greater than the total height of the insert container 11. The insert container 11 is thus at least at its side regions by the frame 13 at the back part 15 is pressed and held. Preferably, the lower end of the insert container 11 is held by the frame 13, that is clamped between the frame 13 and the rear part 15. However, it is also possible that the bottom of the insert container 11 rests on the frame 13. Due to the lower height of the insert container 11 whose filling and emptying opening 18 at the upper edge through the opening 14 of the frame 13 is accessible. In the illustrated embodiment, the insert container 11 on the front side of a handle 19, which serves to remove the insert container 11 from the holding device 12. The frame 13 is formed by a sheet or a plastic plate having a curvature, so that the inside of the frame 13 corresponds to the shape of the insert container 11 at the contact points therewith.

If the frame 13 is released by loosening or unlocking the latching means or closing means 17, it can be pivoted about the axis of the hinge 16, in particular pivoted forward. This position of the frame 13 is indicated in the figure 2b. In this position, the clamping force applied by the frame 13 and the rear part 15 to the insert container 11 is canceled and the insert container 11 can, as in the figure 2b indicated, are taken upwards from the holding device 12. The insert container 11 can then be emptied and immediately re-introduced into the holding device 12. If the condition of the insert container 11 requires cleaning, this can be brought to a cleaning station. In the meantime, another holding container 11 can be introduced into the holding device 12. Even if the insert container 11 is damaged, in particular, if the transparency of the insert container 11, for example by scratches, is reduced or completely lost, this can be replaced by a new insert container 11. The latching or closing means 17, which must be actuated to open the holding device 12, may for example be a lock. As a result, access to the insert container 11 and a stealing of the insert container 11 can be avoided by unauthorized persons.

In order to reduce the space required for the storage of the insert containers 11 and to facilitate their transport, the insert containers 11 preferably have a shape in which the cross section from the opening 18 to the bottom is reduced or at least remains constant. FIG. 3 shows a possible shape of the insert container 11. With this embodiment of the insert container 11, the insert container 11, as shown in Figure 3, are stacked in one another.

Finally, FIG. 4 schematically shows a possible way of producing a feed container 11 for the waste container 10 according to the invention. By the discharge of the insert container 11 from the manufacturing process of PET bottles, the insert container 11 can be produced in a cost effective manner. In a first step, so-called "preforms" are produced. As precursors of PET bottles, these preforms already have finished screw threads. Subsequently, the preforms are softened again, for example at 100 ° C, stretched with compressed air and blown to a bottle (stretch blow molding process). These bottles, which are mass-produced, can be heated again to produce the insert container 11 according to the invention and brought into the desired shape for the insert container via a further stretch blow step become. It is also possible to produce the insert container 11 according to the invention directly from a preform, which then has no screw thread in this case.
